Question

我的应用正在抛出此错误：

[INFO] Caused by: java.lang.ClassCastException: com.google.apphosting.utils.security.urlfetch.URLFetchServiceStreamHandler$Connection cannot be cast to javax.net.ssl.HttpsURLConnection
[INFO]  at info.modprobe.browserid.Verifier.verify(Verifier.java:76)

导致错误的代码是：

        URL verifierURL = new URL(this.url);
        String response = "";
        HttpsURLConnection connection = (HttpsURLConnection) verifierURL
                .openConnection(); // error here...
        connection.setRequestMethod("POST");
        connection.setRequestProperty("Content-Type",
                "application/json; charset=utf-8");
        connection.setDoOutput(true);

尝试使用此library进行Mozilla个人身份验证时。我想知道可能是什么问题，因为GAE URL Fetch Service支持HTTPS。

Answer 1

尝试

HttpURLConnection connection = (HttpURLConnection) verifierURL.openConnection();

而不是

HttpsURLConnection connection = (HttpsURLConnection) verifierURL.openConnection();

它将创建它所需的内容，也适用于HTTPS，但不要强制转换为HttpS，因为它使用类（URLFetchServiceStreamHandler $ Connection）taht扩展HttpURLConnection而不是HttpsURLConnection

用于HTTPS的GAE URL提取服务
